SAS (SONICLEAR ATTENUATION SYSTEM) FINISH The Natural Satin SAS finish brings out the beautiful characteristics of the wood used in the drum, but also allows the shell to vibrate fully due to its very low mass. Thicker finishes such as High Gloss increase the shell's volume, resulting in a shorter sustain and a more focused sound. Features SONICLEAR™ BEARING EDGE Allowing the drumhead to sit flatter on the shell, making better contact. The result is a stronger and deeper fundamental pitch, effortless and consistent tuning, and a significantly expanded tuning range. For the serious player, the increased head-to-edge contact increases shell vibration, allowing the sonic nuances of the hybrid shell to stand out. SONIC SAVER™ HOOPS The inward flange and extra weight of the Sonic Saver hoops help to focus and control the sound of the drums. The projection is more down than out and will provide more of a vintage or closed tone. SAS(SONICLEAR™ ATTENUATION SYSTEM) FINISH Based on the proprietary SONIClear™ Attenuation System (SAS) sonic effect scale developed through the Mapex Design Lab. From SAS 0 to 3, the selection on the finishes giving the snare drum a distinctive sound by the individual artist. MASTER TUNE LUG™ The elegant design of the Black Panther lug has been revised by the Design Lab to form the new Master Tune Lug. The first truly “Locking Tube Lug”, the Master Tune Lug utilizes a small body for the least amount of metal-to-wood contact. A Design Lab-exclusive pressured locking mechanism is outfitted on every lug to keep the drum in tune, show after show. AIR FLOW VENTING The venting is key to the feel and the overall resonance of the shells. Through painstaking testing, each Chamber Specific approach has led to a formula of multiple vent holes in BP Design Lab snare drums. These air flow vents are placed at the *Nodal line with the lugs, so as to not affect the resonance of the shells.
